Can I just say that, for every story like this, there are many stories we don't hear about because SW, midwives, Child Protection people have managed to successfully intervene. Not only by taking the children into care (the nuclear option) but because the lower-level interventions of support and education have been offered, accepted and implemented.
Those "saves" can never make the news (it would be breaching confidentiality for a start, and "saves" are not news, because "nothing" has "happened" except for normal lives, rolling forwards) and it's a shame, really, because we get a ridiculously skewed view of the work that child protection people, social workers and so on do - and what they achieve.
